Studies: Abjuration and evocation shaped by mathematical formulaeManner: Measured and courteous, Vesper speaks as if every conversation deserves a careful proof.Focus: A brass astrolabe ring whose tiny arms she turns to trace spell geometry in the air.Quirk: She taps a rhythm of seven beats against any surface before attempting something risky.Wants: Find the missing observatory lens and determine whether its destruction was an accident or a deliberate attempt to hide a discovery.Vesper Arclight was apprenticed to an observatory’s arcanists until a miscalculated experiment fractured its central lens. She salvaged this codex and now studies the boundary between precision and instinct.
